• Uses: Hydrazine Hydrate used as a reactant in the cyclizations of pyridinones. It is also used in the study of nanocrystal semiconductors, participating in the functionalization and passivation of surface states. It is widely used as a reducing agent or an intermediate of synthesis in various industrial sectors like water treatment (effluents, industrial boilers), chemical treatment process (metals, mine extraction) or active ingredients synthesis (pharmaceuticals and agrochemicals). Hydrazine hydrate is used as a reducing agent in synthetic and analytical reactions and as a solvent for many inorganic compounds. It also is used with methanol as a propellant for rocket engines. Another application is catalytic decomposition of hydrogen peroxide.
